Long Xiangtian walked to the door, frowned, thought for a moment and said, "Do you have a laptop? Lend it to me!" He thought of a way to solve this problem!
Zheng Yuan was a little confused as to what Long Xiangtian wanted his computer for, but he still agreed and took out the laptop from his room.
Long Xiangtian was seen sitting on the ground, typing on the computer keyboard with his fingers nimbly. After a while, the original screen went black, and then a series of codes appeared.
Long Xiangtian's hands never stopped moving. Zheng Yuan and the other two could only see his fingers flying left and right, while the code on the screen flashed quickly. "Ding!" Long Xiangtian finally hit the Enter key, and a red dot appeared on the screen, surrounded by a network of silk threads.
"Cell phone!" Long Xiangtian stretched out his hand. Liu Ran was shocked at this time. He wondered how Long Xiangtian knew everything, even hacking skills. When he heard Long Xiangtian's order, he handed it to him subconsciously.
"Fruit phone? No, give me mine!" Long Xiangtian took the phone, flipped it twice, and then said to Liu Ran.
Long Xiangtian is now connecting to the satellite signal. Every electronic product, including monitoring equipment, has a certain signal. You just need to find this signal to track it, just like the GPS positioning on a mobile phone.
However, foreign Apple phones are not eligible because the satellites they use are not from their own country. Only domestically produced phones can be used.
Taking his somewhat old mobile phone, Long Xiangtian fiddled with it for a while, and soon a red dot appeared on the screen. At this time, Long Xiangtian began to tap on the computer keyboard.
As Long Xiangtian tapped, the red dots on the computer screen kept moving and flashing, and the network-like lines also kept changing, appearing and disappearing, and finally returning to darkness.
"Okay, I have blocked all the signals in this room. Don't worry whether there is surveillance or not!" Long Xiangtian put down his computer and mobile phone, stood up and said to the three people.
"Is this accurate?" Liu Ran was a little worried. Long Xiangtian glanced at him. This was the method of chasing the enemy and guarding against enemy surveillance that he learned in the team. How could it be inaccurate
"Don't worry, there is nothing bad in the team!" Long Xiangtian simply explained the principle in two sentences. Use the mobile phone to contact the satellite, and then use the computer to destroy the signal. He didn't say too much, and anything else would be a secret of the team.
Liu Ran and Yuan Qi have always blindly trusted Long Xiangtian, so they were relieved after hearing his explanation. Although Zheng Yuan still had some doubts, he did not say much. After all, this was a matter involving them, and Long Xiangtian would not do anything without certainty.
After solving the problem of possible surveillance threats, now the time comes to unlock the door. This is not a difficult task for Long Xiangtian. He just used a small piece of wire and hooked it lightly with his finger. He heard a "click" and the door opened.
"Wow, Master, how come you know everything? I also want to stay in the team for a few years and become an all-round talent when I come out!" Liu Ran was very excited.
Long Xiangtian looked at him with amusement. Did he think that the team was such an easy place to stay? When there is a war, you really need to fight hard, so everyone in the team is a hero.
Long Xiangtian pushed open the door and several people walked in. Liu Ran, Yuan Qi and Zheng Yuan mostly focused their attention on the decoration, only Long Xiangtian was observing the layout.
Long Xiangtian went straight to the desk, where there were neatly arranged books and several folders, as well as a pen holder with several pens in it.
Long Xiangtian first opened the folder and looked at the contents inside. They were all unimportant things, so Long Xiangtian didn't care about them anymore. This time he came here to get evidence that could directly convict Boss Zheng.
Long Xiangtian searched all the drawers, but found nothing but some documents and information about his business. Although there were some minor problems, they were of no great use.
Where should the things be placed? Long Xiangtian thought carefully, searching every inch of the study. Suddenly, his sight stopped at a place where a picture was hung.
Long Xiangtian walked over and stroked the edge of the frame with his fingers. It connected with the wall seamlessly without any sense of abruptness, but Long Xiangtian felt that there was something wrong here.
"What's wrong, Master? Is there something wrong with this painting?" Liu Ran and others looked at Long Xiangtian who seemed to be thinking seriously, and began to study it as well. However, after looking at it for a long time, they couldn't feel that there was anything wrong.
"It's written like this in martial arts novels. Usually there must be secrets hidden under the portraits in the study!" Yuan Qi propped up his little head and said it seriously.
Long Xiangtian patted his head, and his originally serious mood suddenly relaxed. He smiled and said, "Novels are all lies, how can they be trusted? However, this painting does have some problems. You see, it is placed a little too deliberately!"
But what exactly was the problem? Long Xiangtian tried to take the portrait down, but it was surrounded by nails on the wall. Not only could he not take it down, he couldn't even move it left or right!
It was precisely because of this that Long Xiangtian firmly believed that it was suspicious. Most people hung portraits directly on the wall with a rope at the back, which made it easy to take them down when necessary. It was rare to nail them directly with nails.
"Zheng Yuan, come and take a look. Do you have any ideas? Or what your father does every time he comes in? Think about it." Long Xiangtian said to Zheng Yuan. After all, he had lived in the house for so long, there might be clues.
Zheng Yuan looked at the painting carefully, and he indeed did not find anything wrong. As for what his father was doing, he had no idea because he had never been here before.
"Every time he comes, he will ask someone to bring in a pot of water, but there is nothing wrong with that. It is inevitable to want to drink water while working!" This is the only thing Zheng Yuan knew, but he felt it was useless.
Long Xiangtian fell into deep thought. Drinking water was not strange, but it was strange that he could remember to get water every time before going in. "Liu Ran, go get a glass of water!"
Liu Ran obediently went to get the water. Long Xiangtian took it and stood in front of the portrait and thought for a while. He reached out and touched the drawing paper, then slowly poured the cup of water on it. Seeing the portrait being soaked little by little, Liu Ran and others became a little anxious.
"Why did you wet the painting? Do you suspect the answer lies here? And that's too obvious. Once the drawing paper is wet, it can't be restored to its original state!" This was the first time that Liu Ran spoke to Long Xiangtian in this "are you kidding me" tone.
Long Xiangtian shook his head and ignored their doubts. He was now staring at the drawing paper intently, hoping to see some other changes. Just when Long Xiangtian was about to give up and even suspected that he had guessed wrong, there were finally some changes in the portrait.
After the drawing paper got wet, it was stuck to the wall. A red circle could be vaguely seen in the center. Liu Ran also noticed the difference at this time, and immediately shut up and stopped talking, and even reached out to poke the red circle.
"Don't move!" Long Xiangtian stopped Liu Ran from doing that. Liu Ran looked at his hand that was about to go up, pursed his lips, and took it back.
At this time, Long Xiangtian took the computer again. He had discovered the abnormality when he blocked the signal outside before, but he felt that this was just a signal receiver, and the monitor could receive and send at the same time, so he didn't pay much attention to it.
